A Preliminary Study of Proteomic Analysis on Caseins and Whey Proteins in Donkey Milk from Xinjiang and Shandong of China

The proteomics of donkey milk from China’s major producing areas have not been well documented. To explore the protein profiles China, this study preliminarily investigated caseins and whey proteins in products two using quantitative approach. Total 15 genetic variants 620 were identified relatively quantified. Functional categorization was clustered into 46 terms based on Gene ontology (GO) 42 Brite B classes Kyoto Encyclopedia Genes Genomes (KEGG). Six seven isoforms firstly observed milk. Whey including α ‐lactalbumin, β ‐lactoglobulins lysozyme identified, but no immunoglobulins or lactoferrin determined. An unprecedented low ratio casein/whey indicated that very good sources with high biological value. This enhanced knowledge composition established differentially expressed selected China.
